Abstract
The oil content of the leaves and flowers of Lantana camara L. (Verbenaceae) known as \"verbena oil\" was determined by water distillation (0.1% and 0.2%) respectively. The physical and chemical properties such as specific gravity, refractive index, optical rotation, acid value, ester value and saponification value were determined according to standard methods and the results were compatible. The oils were subjected to antibacterial screening against two Gram positive and two Gram negative bacteria and the flower\'s oil gave good results against E.coli and Ps. aeruginosa. Analysis of the oils by TLC and combined LSC and GLC made possible the identification of the main constituents of the oils. The major component of the flower oil was =538;-elemene (36%), while =538;-caryophyllene was the major component (35.96%) of the leaf oil. Technical difficulties and lack of apparatus and standard for analysis as well as library data for identification, prompted us to compare results of analysis with available data in the literature with emphasis laid upon Indian verbena oils
